Beit known that l, HAR Y H. Inn, a citi zen of the United States of America, residing in La Grange, county of Cook and State of Illinois, have invented certain new and useful Improvements in Governors, of which the, following is .a specification.

Myinvention relates to speed governors V and has to do more particularly witlrgovernors for use in connection with automatic calling devices, such asa're commonly employed in automatic and semi-automatic telephone systems for controlling the automatic switches which are located at the centraloffice, and are used for establishing connections between calling and called subscribers lines.

For the purpose of illustrating my in;

vention, I have shown my governor connected to an automatic calling device, but .it is to he understood that I do not wish to limit its use to such, as it is adapted for use in connection with many other devices.

In the present automatic telephone systems of the two-wiretype, it is necessary "to maintain the speed of the calling device constant and any slight change in speed oi the device will affect the apparatus at the main exchange, causing an incorrect operation of the same. p 7

An object of my invention is to provide a o-verning device which may be readily ad usted without the use of special tools, and which when once adjusted remains in such adjustment and maintains the speedof the calling device constant. p

The governing device of my invention embodiesdesirable features and advantages in a simple, efficient and economical manner,

and theseifeatures will be more fully dc scribed in the ensuing specification.

in part of said co -pending application.

Referring nowmore in detail to my. in-

yention as illustrated, the calling device associated Wlth the, governor mechanism coinprises a main mounting plate A, which sup ports the: calling device mechanism, a finger hold actuating member B, and a bridge plate C for supporting parts of the calling device. t

grallyfwith it, the said pinion 3 'meshing i with a gear wheel 4 of a trainof gearing which operati vel'y connects the, governing mechanism to the motive power ofithea call"- ing devicei Amember 5 isstaked'to the main mounting plate A andservesas a hearing forithe shaft 2 andxalso-ase braking surface forthe weighted meinbers 6 and? of the-governor mechanism. Y. The weighted members 6 and 7 of th'egovernor are'pivot ally: supported on a mounting plate 8- hy 1??? means of the pivot pins 9 andlO. The end of the governor shaft 2 is threaded. and has screw threaded engagement with a suitable vtapped orifice'in the mounting plate 8,-to

thus rotatably' secure the governor'mechanism as a 'whole to the-mounting plate Am The pinion 3 onthe governor shaft 2 meshes with'a gear wheel upon the shaft- 11, Which-shaftll hasin turn a'pinion #12 integrally, formed with it. The pinion 70 fullandcomplete understanding of the gov.-

75 :The present application is a continuation l 13 upon the main shaft 14, and this train of gearing thus outlinedconnects the governor mechanism G with the main shaft 14; A

plate 15 of comparatively thin metal is provided -ancl, -fo rmed integrally with the plate 15,- are angular downwardly extnding-portions 16 and 17provided with arcuate spring arms 18 and 19. The plate 15 is provided with a rectangular shaped slot 20,v-through which the threaded end.21 of the shaft 2 projects when the said plate 15 is in place, as illustrated in Fig. 4. The spring arms 18 and 19 engage respectively the weighted members 6 and 7, and thefsaid plate is held in place by means 'of1anut-22which has screw-threaded engagement with the threaded-end 21 of the shaft 2.7 A member 23 is provided and has an orifice 24 of a size to permit it being slipped over the threaded end portion 21 of the shaft 2, and rests between the plate 15 and thenut 22. The

member 23 is provided with a shoulder portion 25 which fits down into the'slot 20 of the plate 15. The shoulder portion 25 of the member 23 isfsuch as not to permit rotation of the plate-15 relative to the member 23,-but to permit only'lateral movement of th plate 15 relative to themember 23. The shoulder portion 25 of the member 23 is slightly greater inthickness than the plate 15 so that'when the nut 22 is tightened, the

plate 15 is held against rotation but'not against lateral movement,- for purposes as will presently be described. v

;-The governor mechanism G is operatively associated with the train of gearing before mentioned, and when the finger hold-actuating member B is rotated in a clockwise die rectionto setthe calling device to transmit a certain number of impulses, the gear 13 and floating ratchet 30, which are loosely mounted-upon the mainshaft 14, remain stationary, while the shaft 14 and dog 31 are operated in a clockwise direction so that the arms 32, 33 and 34 ride over the wings 35 of the floating ratchet 31 until the :arms32 and I shaft 14 and dog'31, all of which are secured- 34 rest in the desired'wing. 35 of the'fioating ratchet- 30. Upon the return movement of the finger hold actuating member 13' the to the shaft 14, also return therewith and as the arms 32 and. of the dog 31 now engage thedesired wing 35 of the ratchet 30, the

members 6 and 7 are pivotally secured tothe mounting member 8, they are forced out by centrifugal force against the tension of the spring arms 18 and 19. The forcing out of the free ends of the weighted members fiand 7 causes the pivotedends of the members 6 and 7 to be forced against the Eeripheral surface 40 of the member 5, and

crum of the weighted members 6- and 7, the weight of the said members is multiplied in forcing the engaging surfaces of the weighted members 6 and 7, against the peripheral braking surface 40 of the member 5.

i The slot 20in the plate 15 as before'mentioned permits lateral movement'of the plate 5, so that should therebe a slight difierence of tension between the spring arms 18 and 19, it is overcome by permitting the plate '15 to move slightly either way,depending upon ue to the. engaging surfaces of the weighted members I 6 and 7 being i'nclose proximity to the ful-' the tension ofthe' said arms 18 and 19, thus equalizing the tension of the spring arms. 18 and 19. The action of the tension of the spring members Band 19 upon the weight ed members 6 and 7 may be lessened or increased to increase or decrease the speed of rotation of the calling device, and to accomplish this the nut 22 is loosened and the member 23 and plate 15 are rotated in one directlon or the other, relative to the weighted members, to lncreasethe action of the spring tension or to decrease the action of the springtension upon the weighted members 6 and 7, whichever the case may demand. I v the free extremity of the springs 18Ya-nd 19 towards or away from the fulcrumed points of the weighted members will decrease or increase the action ofthesprings 18 and 19 upon the weighted members when they are rotated.

While I have illustrated and described my invention operating in connection witha certain type of automatic callingdevice, I do not wish to be limited to-the'same, as my invention may be adapted to cooperate in conjunction with other devices, and changes and modifications may readily suggest themselves to one skilled in the art. Therefore, I

It is apparent'that the relation of do not wish to be limited to the exact struc- 1.
